Introduction

These commands are shown in the YouTube tutorial: xxx

Based on the official docs with the addition of the automatic sending of ready\r\n on boot, as required by the firmware of my boards (these ones).

Rules for all boards:

• Open Module Configuration -> Set module to Generic (18). Click save.
• Now, depending on the number of relays on your board, do the next 1, 2 or 4 changes:

jlblancoc

function [] = dibuja_dep(x, Fs)
% Dibuja la densidad espectral de potencia (dep) 
% o power spectral density (psd) de una señal "x" muestreada a una
% frecuencia de muestreo "Fs" (Hz)
N = length(x);
X = fft(x);
X = X(1:N/2+1);
psdx = (1/(Fs*N)) * abs(X).^2;
psdx(2:end-1) = 2*psdx(2:end-1);
freq = 0:Fs/length(x):Fs/2;
